The zombies made a very short appearance. They were only shown in UnderFist!!! The Rebellion! Three zombies were shown:One was a general with the back of his head missing, and his purple brain sliding out. The other one was bleeding ans had a missing limb. he also was missing an eyeball. The third one was shown to be standing on stilts and bleeding. There might be another mini-story that shows zombies, but it has not been confirmed.
